Generally, most of the biomass size reduction devices
are rotary machines with cutting force applied by
cutting elements through rotary tangential action at a
high velocity for mechanical harvest. Yet in order to
obtain more accurately force-displacement data, it was
inevitable to mainly focus on linear saw blade cutting at
a quasi-static speed in this study. Hence, further studies
may be required to investigate the advantage of bionic
disc saw for cutting different biomass with different
speeds.
